Answer:
Koverall [NO]^2 [Br2]
Balanced chemical reaction equation;
2NO + Br2 ⇄2NOBr
Explanation:
Consider the first step in the reaction;
NO(g) + Br2(g) ⇄ NOBr2(g) fast
The second step is the slower rate determining step
NOBr2(g) + NO(g) ⇄ 2NOBr(g)
Given that k1= [NOBr2]/[NO] [Br2]
k2= [NOBr2] [NO]
The concentration of the intermediate is now;
[NOBr2]= k1[NO][Br2]
It then follows that overall rate of reaction is
Rate= k1k2[NO]^2 [Br2]
Since k1k2=Koverall
Rate= Koverall [NO]^2 [Br2]

Explanation:
Ionic compounds are composed of crystals. The crystal structure of an ionic compound is responsible for its hardness.
A crystalline solid contains a well organized structure which enables it to be hard and have a particular geometric shape as well defined melting point.
Hence, all the observed characteristics of NaCl are the result of its crystalline structure.
